Parse error: syntax error, unexpected T_FUNCTION on plugins page
I have just migrated my localhost WordPress site to my live server using the this tutorial.
For some reason, when I try to activate ANY plugin from within WordPress, it gives me the following error message:
'Parse error: syntax error, unexpected T_FUNCTION in /var/sites/d/sitename.co.uk/public_html/wp-content/plugins/elementor/elementor.php on line 55'

Query the title of the page to show posts with matching category in the loop
In the archive page for a custom post type I have this query:
$the_query = new WP_Query( array( 'category_name' => 'Bordeaux' ) );
Then in the loop I have:
if ($the_query->have_posts() );
Et cetera.
The loop correctly searches my posts and displays all posts with the category 'Bordeaux' on the page.
I would like to alter this query so that instead of searching for the text string 'Bordeaux', it will query the title of the page and search for a category with that name.
This will allow me to have just one .php file for all custom post types, rather than individual ones.
I tried the following but it didn't work:
$the_query = new WP_Query( array( 'category_name' => echo the_title(); );
Any help much appreciated! | you don't need to echo the title out.

$the_query = new WP_Query( array( 'category_name' => get_the_title() ); | stackexchange-wordpress | {

Dynamic assign a custom template to custom post type posts

Conditionally including JS based on whether ACF field is set
I'm trying to include a javascript file in the head of a WordPress page based on whether or not a particular field nested inside a flexible content field nested inside a repeater is set or not.

WordPress Plugin Boilerplate: Addition of 3rd party scripts and styles
I am using the Wordpress Plugin Boilerplate (wppb.io) to build a custom plugin and I am not quite sure where to place a 3rd party script and a 3rd party style for a jQuery Timepicker.
Because the timepicker will be used only in the admin area, is it okay to just place the 3rd party files into the `admin/js` and `admin/css` folders respectively, along with my custom scripts and styles for the admin area?
UPDATE: According to top contributer of the boilerplate, Tom McFarlin you suppose to place them inside the respective `css` and `js` folders, so I have marked Samuel's answer as correct. Additionally, Tom states that if we are talking about 3rd party libraries, it would be good to create a `lib` subdirectory inside the `css` and `js` folders and place them there. | **IMO** , since
> the timepicker will be used only in the admin area
, then YES, it is okay you place the 3rd party files into the `admin/js` and `admin/css` folders respectively.
With that, you _(also other developers)_ can be able to clearly know where to find files that corresponds to their respective views.

Demystifying and understanding shortcode nomenclature
A code snippet from the Tuts Plus →
function link($atts, $content = null) {
extract(shortcode_atts(array(
"to" => '
), $atts));
return '<a href="'.$to.'">'.$content.'</a>';
}
Source Link →
# Question →
How to reproduce `"$to"` in the shortcode?
I tried this →
`[link $to= " But this didnt worked. | It's just `[link to= "
This is a textbook example of why `extract()` is bad. You can't easily tell where variables are coming from. `extract()` creates variables out of an array with the keys becoming the variable name. So this part:
extract(shortcode_atts(array(
"to" => '
), $atts));
Is creating an array with a `to` key, set to ` if it's not defined in `$atts`. Then it's `extract()`ed so that the `to` key becomes `$to`.
You should avoid using `extract()` and just use the `$atts` variable:
function link($atts, $content = null) {
$atts = shortcode_atts(array(
"to" => '
), $atts);
return '<a href="'.$atts['to'].'">'.$content.'</a>';

Wordpress Multisite - Auto enable theme
I have a server that uses themes from our private repository, and I'd like to auto enable the themes as soon as they exist in the wordpress themes folder.
Right now I have to login as administrator and enable the theme network-wide so the adminisrators can choose the theme.
Is there a way to configure wordpress network to AUTO enable the themes? | Unfortunately, no.

How to restrict wp generate attachment metadata() to certain intermediate image sizes
In Wordpress, we have added our own intermediate image sizes to the standard Wordpress sizes using add_image_size().
Using our own admin interface to upload images, we then use wp_generate_attachment_metadata() to create all thumbnails and save them to a predefined folder on the server.
However, we would like to restrict wp_generate_attachment_metadata() to generate our custom defined image sizes ONLY and ignore the Wordpress standard sizes.
Is this possible?
Thanks in advance for any help! | `wp_generate_attachment_metadata()` uses `get_intermediate_image_sizes()` to get the sizes to work on, which makes them filterable via `intermediate_image_sizes`.
Additionally, you can filter them after cleanup with `intermediate_image_sizes_advanced`, the result should be the same. | stackexchange-wordpress | {

Insert HTML content in WP Query at specific point

I've done this previously with a WP_QUery using an `if( $query->current_post == 4 )` statement.
How can I achieve the same effect with a `have_posts` loop?

Is a dynamic website with lots of urls possible with wordpress

Is it possible to build such a website in WordPress, If yes, Do I need to create a new theme from scratch, Or I can do this with any theme | WordPress URL handling is data-centric.

If you are considering migrating another site to WordPress you would have two typical options:
1. Migrate the data to native WP data types, such as custom post types and taxonomies. In this case you get URLs working "for free".
2. Integrate alternate data structures/source into WP site. In this case you preserve data as is, but you would need to spend significant effort to implement custom rewrite rules and how should WP _retrieve_ the data from custom sources. | stackexchange-wordpress | {

responsive.css in the Wordpress should be prioritized

Whatever I write in `responsive.css` should be prioritized(that means CSS written here should override everything else written in style.css.), but that is not happening. Is there a way to achieve it through something that WordPress provide?
# Update →
the whole idea is not to use `!important`, but still when the website is loaded in smaller screens than responsive.css should dominate or override style.css without using any `!important` tag. | If you want to make sure the second stylesheet loads after the first, you can use the third argument of `wp_enqueue_style` to set a dependency, eg:

As for having **all** the styles in _responsive.css_ override _style.css_ , that is going to entirely depend on the specificity of the targeting in each stylesheet, CSS being a Cascading Style Sheet, it would be worth researching exactly what that means if you aren't fully sure how it works. | stackexchange-wordpress | {

However if you have a backup of your database, you _should_ be able to retrieve the `active_plugins` option and reapply it through say phpMyAdmin.

Understanding the query string after .htaccess rewrite

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

Call add_action() in function wordpress

Get and show all of the available categories
I know that there are a few ways of doing this but for everything that I have tried I can only manage to get the first category. For example:
<?php echo get_the_category_list(); ?>
Only shows one. Like:
<?php
foreach((get_the_category()) as $category){
echo $category->name."<br>";
echo category_description($category);
}
?>
Shouldn't this functions get me the full list of existing categories? | It should be noted that both
<?php echo get_the_category_list(); ?>
and
<?php
foreach((get_the_category()) as $category){
echo $category->name."<br>";
echo category_description($category);
}
?>
display ALL categories that are assigned to the current post in the loop.
From your question's title, I understand that you want to display all available categories that exist in the website, so `wp_list_categories()` is more suitable. So using:
<ul>
<?php wp_list_categories(); ?>
</ul>
will return a list of all categories that have been assigned to at least one post. You can see the documentation for the function here. | stackexchange-wordpress | {

How to set permalinks when posts and pages have different URL structures?
I've been hired to migrate a custom CMS to Wordpress.
The blog page is a subpage of "About Us": `/about-us/blog/`
Each blog post has a URL of `/about-us/blog/xxxx/postname`, where xxxx is the year it was posted.
The site has 10 parent pages, each having `x` sub-pages, so I need webpages to have a URL of `/parent-page/sub-page`
Is it possible to set permalinks that will work for both webpages and blog posts with the above URL structure? TIA. | From quick test you _should_ be able to just use Custom Structure for it (in Settings / Permalinks):
/about-us/blog/%year%/%postname%/

Align reCaptcha to right on Contact Form 7
I am running a wordpress site with contact form 7. I have signed up to reCaptcha and everything is working fine except all the fields on the form are right aligned but the reCaptcha is aligned to the left.
Is there anyway to align it to the right like the rest of the fields?
Heres a screenshot from my local machine: ![Picture of reCaptcha aligning to left on contact form 7]( | You can't do that directly inside the CF7 plugin you need to modify the CSS.
Add the following to your theme's _style.css_ file:
.wpcf7-recaptcha > div {
margin: 0 0 15px auto;
}
PLEASE BE NOTED:
If you add the above code, it will take effect to all your recaptcha fields in every forms on your website.
Often times, we would like to only do this to a certain form, this is how you can do it:
First: Add an ID to the recaptcha in Contact Form 7
[recaptcha id:enquiryFormRecaptcha]

Force default OG:Image - Yoast SEO

add_filter('wpseo_pre_analysis_post_content','mysite_opengraph_content');
function mysite_opengraph_content($val){return '<img src=" alt="Rafaël De Jongh - Web Developer | 3D Artist"/>' . $val;}

add_filter('wpseo_twitter_image','default_opengraph');
But which allows to add this to the OG:Images rather than replace it. | The action that allows an OG image to be added seemed to be the thing I was looking for, so much for proper documentation on their side.

function add_default_opengraph($object){global $default_opengraph; $object->add_image($default_opengraph);}
add_action('wpseo_add_opengraph_images','add_default_opengraph');
function default_opengraph(){global $default_opengraph; return $default_opengraph;}
add_filter('wpseo_twitter_image','default_opengraph');

Best way to query posts and order by relevancy to query

How to migrate a website based on a custom database to wordpress?
My question is similar to that one which was closed for being too broad, so I'll try to be clearer.
**What I have** : a sqlite database (single table) containing over 50'000 posts (with fields like author, content, date, etc.). It stems from scraping a huge static, html-only website.
**What I want to achieve** : displaying those posts in a standard WP installation.
**My approach** : I would
1. Initialize an empty WordPress website
2. Write a script that reads a post from the original DB and writes it into the corresponding fields of the WP database (ID -> ID, author -> author, date -> date, ...)
3. Run the WordPress engine engine and expect the posts to appear
**My question** : is this approach likely to succeed, or should I avoid this futile work and consider other solutions? | I don't see any reason for this not to work. I have done similar transfers few times, and if you transfer all data correctly, and if posts in the wp_posts are well formed, with all data present (status, type...), it will work.
The tricky part might be the data that can't fit into wp_posts, and it should go into wp_postmeta, you need to take care of proper post ids. Also, make sure to use correct format for date field, make sure to have both post_date and post_date_gmt filled, guid (some unique string for each post, WP uses URL by default), and make sure author ID's are correct. | stackexchange-wordpress | {

Thank you. | The variable **$category** is a single category (has to be set somewhere before), and the **$category->term_id** is the ID of that category.
And, **array($category->term_id)** is an array with one element only, and that element is category ID. **'category__in'** argument requires an array of categories, and if you have one category even, it has to be placed in the array.

Show current user posts in custom post type query

}
}
return $query;
}
Can anyone help me please? | There are 2 fundamental problems here:
## Problem 1
`pre_get_posts` lets you modify a query before it happens, and in this case you're modifying the main query before it happens.
But you do this:
if ( get_post_type() == 'saved-orders' ) {
`get_post_type` shouldn't work here as it's too early, the main query hasn't happened yet. Instead, lets ask the query object:
if ( 'saved-orders' === query->get( 'post_type' ) {
## Problem 2
This is a syntax error, and not valid PHP:
$query->set( 'author' => $current_user->ID );
`=>` is only used in 2 situations:
array(
'key' => 'value'
)
and
for ( $array as $key => $value )
Neither of which are function calls. The correct way to call the `set` method is:
$query->set( 'queryvar', $new_value );

What is the difference between WordPress Business plan vs self hosted WordPress (WordPress developer perspective)?
**Short version of question** : : I am not asking the difference between WordPress.com vs WordPress.org.... I am asking difference between WordPress.com Business plan vs WordPress.org
**Long version of question** :
> According to < **WordPress business plan allow to install third-party themes and plugins**.
So what is the difference between WordPress Business plan vs self hosted WordPress?
In other word, what are the limitation (WordPress developer perspective) of WordPress Business plan when comparing self hosted WordPress? | First it is important to note the difference between _Business Plan_ and regular WordPress _com_. To my knowledge _Business Plan_ accounts are _not_ hosted on regular dot com grid, but are based on infrastructure of more conventional managed hosting company they've acquired (not sure if completely) while back.
So the closest analogue for it would be a _managed_ hosts that specialize in hosting WordPress, being _more managed_ on a scale and offering some cross-integration with dot com functionality.
Their support materials cover nuances of Business Plan in detail.
In a nutshell difference with _less managed_ self–hosted site seem to be:
* no direct filesystem access (no arbitrary file edits);
* black list of some plugins that are not allowed;
* additional features related to dot com offers;
* ability to migrate to/from regular dot com grid.
Overall I would call it _highly managed_ WP hosting solutions, which is aimed more at site owners than developers. | stackexchange-wordpress | {

Get userdata from url

Thank you | Wordpress already has a url structure for Author information. If you have pretty Permalinks enabled, the URL should read like < .
You can make a new template file named author.php in your theme to manipulate what is shown on this page (add meta information and whatnot).
You can get the author id in the author.php by using `get_queried_object_id()` . Bonus: all the posts by this author are in the loop.
To get the URL for the authors page, you can use `get_author_posts_url( $author_id)` . | stackexchange-wordpress | {

Hope someone can point me in the right direction. Thanks. | I think the function you are looking for is `bp_displayed_user_id()`. That will get the ID of the user whose profile is currently being displayed.
Then, you can check their role like this:
$user = get_userdata( bp_displayed_user_id() );
if ( ! in_array( 'subscriber', (array) $user->roles ) ) {
return;
}
You could also use `user_can()`, but it is best to avoid using role names with `user_can()` and `current_user_can()`, as they are really designed for capabilities and not roles. In fact, you ideally would not check user roles in a case like this at all.

Can I authenticate with both WooCommerce consumer key and JWT?
I want to authenticate against _both_ :
* the WooCommerce consumer key, for system queries _and_
* JSON Web Tokens (JWT), for user queries
I have installed JWT Authentication for WP REST API. But after activating the plugin, previously working queries (that use the WooCommerce consumer key for authentication) fail with:
{'code': 'jwt_auth_bad_auth_header',
'data': {'status': 403},
'message': 'Authorization header malformed.'}
How can I configure Wordpress / the JWT plugin so that they succeed? | Yes this is possible by structuring your requests appropriately.
For system requests use OAuth 1.0 (consumer key as before), but encode it to include the OAuth credentials _in the URL_ not in the headers. Having the OAuth credentials in the `Authorisation` header triggers the JWT error.
GET
* Authorization: `OAuth 1.0`
* Consumer key: FILLED IN
* Consumer secret: FILLED IN
* Other fields: blank
* Headers: blank
* Body: blank
To request a token (for a user-based query), you don't use authorization, you include the user credentials in the body:
POST

How can I authenticate user credentials against a Wordpress instance?
I am running a second web application in addition to Wordpress/WooCommerce. When users log into the second application, I'd like to authenticate them against the WP instance. I am using the REST API for data queries, but that only allows authentication with a consumer key. The API doesn't provide endpoints for user authentication.
Given a username and password, how can I authenticate against a Wordpress/WooCommerce instance? (In other words, from outside the instance.) | The JWT Authentication for WP REST API plugin offers a user authentication mechanism. You will need to:
* install and configure the plugin
* make user authentication requests against the new token endpoint
* optionally use the token to make further queries on behalf of users
* continue using OAuth 1.0 for WP/WC REST queries

Expand author, tags and categories in the Wordpress JSON API
In the V1 of the Wordpress JSON API when you got a list of posts you would also get details of the author, tags and categories.
But in V2 it seems you just get the ID and would need to do another request to get more info.
Is there a way around this, such as a query parameter to automatically expand certain things?
Here is what V1 would return:
tags: {
FM: {
ID: 153647,
name: "FM",
slug: "fm",
description: "",
post_count: 68,
},
FM17: {
ID: 130762795,
name: "FM17",
slug: "fm17",
description: "",
post_count: 31,
}
}
Here is what V2 returns:
tags: {
153647,
130762795
}
At the moment it's not clear if there is any benefit to using V1 over V2 of the api, V1 would infact be easier in this instance. | I figured this out, you have to add _embed=1 to any request so:
> /posts?_embed=1&orderby=date&order=asc
for instance.
Then it will include an `_embeddable` key. Annoyingly all the terms come under here so you have to do some extra work to extract the difference between tags and categories etc. | stackexchange-wordpress | {

get_template_part not working with ajax

How do i send mail with custom Form Data using WordPress
I have a custom HTML form with input types and checkboxes. When I submit this form I want to send a mail will all the form details from the same php. How do I send the email from WordPress? I am pretty new and would thank for ur help. | `wp_mail` is the function you are looking for.
You can take the posted form data (`$_POST['email']`, for example) and then use it to build and execute the `wp_mail` function. The example below was taken from <
$to = $_POST['email']; //[email protected]
$subject = 'The subject';
$body = 'The email body content';
$headers = array('Content-Type: text/html; charset=UTF-8');
wp_mail( $to, $subject, $body, $headers );
Also the above script would need to check for malicious attacks or bad input from the user but the `wp_mail` function will allow you to send email.

Removing Extra Caption tag around image on post of WordPress
I am facing an issue when i use get_the_content() function. It displays the post content but the image in beginning of the content has some extra text around. My code is:
<div class="thecontent" itemprop="articleBody">
<?php echo get_the_content(); ?>
</div>
Output:
![enter image description here](
I also tried
<div class="thecontent" itemprop="articleBody">
<?php $content= get_the_content();
echo apply_filters('the_content', $content);
?>
</div>
But in this case picture isn't showing at all.
Output:
![enter image description here]( | To make sure the shortcode executes, save the content to a variable, then run `do_shortcode` on the saved variable.
<div class="thecontent" itemprop="articleBody">
<?php $content = get_the_content();
echo do_shortcode($content); ?>
</div>
The difference is, echoing just literally echoes whatever has been grabbed. PHP's built-in functions don't have any special way to process shortcodes so they just output as they've been told. By using a WP-specific function, WordPress parses whatever the content is and displays it. This works even if you have no shortcodes in the content. | stackexchange-wordpress | {

Select through customizer the template part to be viewed

Display the 2nd category name of a custom post type without error if its null?

* Post B belongs to category blue

D should be red
E should be blue
F should be blue
G should be yellow
Please help me achieve this using php. I beleive get_post _terms() is what needed here but I struggle to do it. Thanks in advance. | Inside of your loop you can get the terms via `wp_get_post_terms` function. Then, check if two or more terms exist. If they do, then use the function `array_slice` to extract the second term that appears in the array:
$term_list = wp_get_post_terms( $post->ID, 'YOUR_TAXONOMY', array('orderby' => 'name', 'order' => 'ASC', 'fields' => 'all') );
$display_term = (count($term_list) > 1) ? array_slice($array, 1, 1) : $term_list;
However, this does not determine how the terms will output from the database. You may want to define the `orderby` parameter to be something specific so you can predict which term will appear second.

Large Session Tokens
We have a Wordpress site on a shared server that recently crashed due to running out of disk space, because our MySQL binary logs filled up the drive in a matter of minutes. After reviewing what was in them, we traced it down to a single user in this site that has ~3.4MB being stored in the `usermeta` table with a meta key of `session_tokens`. I clicked the Log Out Everywhere option for this user which deleted those records, but then today the same issue started occurring and all of his tokens are back.
Any ideas? I'm not really sure where to begin with this and have no idea how he's amassed this many tokens. I wrote a Wordpress scheduled task that is supposed to delete expired tickets hourly, but since his account had nothing and now today has thousands of them again, the expiration stuff must not apply. I took a peek at some of the expiration timestamps and they are all milliseconds apart, which confirms the scheduled task probably won't help. | No idea what happened, but the end user was having issues with his computer and somehow it was hanging on to those cookies. Since they weren't expired, nothing we did to remove them did a lot of good but getting the end user to clear cookies/cache resolved the issue.

ACF datepicker meta_query Compare Dates in m/d/Y g:i a - Not in Ymd Format
I'm looking for a way to use meta_query to filter out posts with a meta-key value of a date-time in `m/d/Y g:i a` format.
The post-meta is being set by ACF (Advanced Custom Fields).
I want to maintain `m/d/Y g:i a` formatting for output on the frontend, but also need to filter out posts with dates in the past.

'meta_query'=>[
'relation'=>'AND',
[
'key'=>'event_time',
'value'=>$date_now,
'compare'=>'>=',
'type'=>'DATE',
],
]
];
I also know that I can retrieve all posts and use a subsequent loop to discard the posts which don't meet requirements.
But is there a better way to do this? Thanks for reading. | There should not be any need to do this.
Even if an ACF Field is using `'return_format' => 'm/d/Y g:i a',`

Using Blog Parent Slug on Blog Posts Only
_(Advanced warning: novice question)_
I'm trying to find a way to add a blog slug to any blogs I post. Example:
mysite.com/theblog/aparticualrblogpost
mysite.com/theblog/anotherblogpost
Any page created that isn't a blog should use the standard structure: mysite.com/agenericpage mysite.com/parentpage/anothergenericchildpage
How can this be achieved? | Just set your custom permalink structure to:
/theblog/%postname%/
If you have any custom post types used on your site, you’ll need to make sure that they don’t get the /theblog/ prepended to their URLs. To remove it, simply set with_front to false where the custom post types are registered:
'rewrite' => array('slug' => 'portfolio', 'with_front' => false),

I want to use a different icon for Add Media button in the standard post editing form. What's the best way of doing it? | CSS is the way to go here.
Add a new CSS for admin using the `admin_enqueue_scripts` hook in your child theme functions.php (if you don't have one, you're doing something wrong)
function my_admin_enqueue_style() {
wp_enqueue_style('my-css', get_stylesheet_directory_uri().'/css/my-admin.css', array(), '1.0.0');
}
add_action('admin_enqueue_scripts', 'my_admin_enqueue_style');
In your my-admin.css file
/* change the content to another Dashicon */
#wp-content-editor-tools .wp-media-buttons .add_media span.wp-media-buttons-icon::before {
content: "\f104";
}
/* or set a background-image instead (set content to "" in the rule before) */
#wp-content-editor-tools .wp-media-buttons .add_media span.wp-media-buttons-icon {
background-image: url(../../wp-content/uploads/2017/10/my-image.png);

wordpress how to replace url /bar with foo/bar for custom post type
In my wp site there is a custom post type movies.i used cpt plugin to create it. so if i have a post with title `zootopia` it's url appear as ,
`
however i want to change this url to
` when i click view post i want this url to appear in address bar
so i want to replace url `/movie/` to `/parent/movie/`
i tried with `add_rewrite_rule` function
add_action('init', 'add_actor_url');
function add_actor_url()
{
add_rewrite_rule( '^movie/([^/]*)', 'parent/movie/$matches[1]', 'top' );
flush_rewrite_rules();
}
but this doesn't work.it doesn't replace url ` to `
is it really possible.if it's not then is there any other way to do that ? | You just need to set the slug to literally `parent/movie`. If you're doing it in code you set the `'rewrite' => 'slug'` argument to `'parent/movie'`.

Performance impact of using global $post
I have two functions that do the same action: they add a title prefix for _expired_ posts. Which of these functions will affect more the site performance?
function expired_facebook_events_title_prefix_( $title, $id = null ) {
if( is_singular( 'facebook_events' ) && 'expired' == get_post_status() && in_the_loop() ) {
return '[expirat] ' . $title;

return '[expirat] ' . $title;
}
return $title;
}
add_filter( 'the_title', 'expired_facebook_events_title_prefix' ); | There is no significant difference. Both will use a cached version of the current $post, in one you will access it via global $post, in other via functions that will get the data from the $post in the cache.

Adding a title prefix with the the_title filter
I adapted an existing solution to add a prefix to _expired_ posts titles. It works, but it adds the prefix also to the main menu elements and to the Previous/Next links (that are not _expired_ yet). I removed the prefix from the menu elements by adding a supplementary `in_the_loop()` to the `if` condition, but this doesn't removed the prefix from the Previous/Next links. How to solve this?
function wpd_title_prefix_filter( $title, $post_id ) {
if( in_the_loop() && is_singular( 'facebook_events' ) && 'expired' == get_post_status() ){
$title = '<span class="expired-event">[expirat]</span> ' . $title;
}
return $title;
}
add_filter( 'the_title', 'wpd_title_prefix_filter', 10, 2 );
**UPDATE**
I solved it with CSS, but why this happens?
.nav-title .expired-event {
display: none;
} | This happens because **the_title** filter is run when the the_title() or related function is called to print the title, and prev/next links functions run the same the_title filter.
But, the problem here is that you are having general conditions that main post and prev/next fulfil: singular, expired post status and loop. To target the main post only in the single template add condition **$post_id == get_the_ID()** to your **IF** \- **$post_id** is the filter function argument, and **get_the_ID()** get's the ID of the global $post. | stackexchange-wordpress | {

Translate text for empty product
I want to change the text of an empty product. But my code covers all products and I need this only for free products, meaning empty price products. Here is my code:
add_filter('gettext', 'translate_text');
add_filter('ngettext', 'translate_text');
function translate_text($translated) {
if( empty($product->price) ){
$translated = str_ireplace('Weiterlesen', 'Contact US', $translated);
return $translated;
}
}
This code is working perfectly, but it covers all products. I mean, the empty price condition is not working as expected here. | In your function 'translate_text' variable **$product** is not initialized, so the price is always empty. You need to provide the $product for use inside the function, consider the function, it should be global. Try modifying function:
function translate_text($translated) {
global $product;
if ($product && empty($product->price)){
$translated = str_ireplace('Weiterlesen', 'Contact US', $translated);
}
return $translated;
}
If your $product is set as global, this will work, if not, you need to set it like that, or think of another way to provide this function with outside variable. | stackexchange-wordpress | {

Duplicate slug/permalink issue
I have a website which lists concerts and festival and some of them are returning each year. I have made a custom taxonomy where you can add the post to a year (2017, 2018, 2019 and so on). I also added the custom taxonomy to the slug (/shows/%archive%/%postname%/ – where archive is the year the post is in).
This works all like it should, URLs are now: /2017/name-of-show or /2018/name-of-festival
But when I re-add a festival for the next years edition I still get the URL with a -2 at the end, because of the post slug is already taken, while it should be /2017/festival-name and /2018/festival-name instead of /2018/festival-name-2
Am I missing something, or is this just not possible to do with duplicate names/slugs? | You can do that using Custom Permalinks Plugin, you need to add a full slug manually `[shows/2017/any]`.
It also allow you customize your permalink: `[anyname/another/2017/example/slug]`.

Multiple Domains and Subdomains Using Multisite Installation

www.example.com (redirects to example.com)
sub1.example.com
sub2.example.com
example.net
www.example.net (redirects to example.net)
sub1.example.net
sub2.example.net

Can not set custom title on some WordPress setups
I'm having a bit of an issue changing the title on a custom page. Most the time the standard code works, but for whatever reason on certain WordPress setups I am unable to change the default title.
What usually works, but is not working in this situation:
function customtitle(){
return "custom title";
}
add_filter('wp_title', 'customtitle', 10);
I'm also aware of the issues with changing custom titles and the yoast plugin. On the current WordPress setup I'm working with yoast is not installed. I wanted to know if there was another hook or method that I can override the title over the current default title. | This is most likely due to difference in your theme's support. Some themes render the title by using the `wp_title` filter, some by using `pre_get_document_title`. If your theme has this line in its `functions.php` file:
add_theme_support('title-tag');
Then you need to use the `pre_get_document_title` filter, as follows:
add_filter('pre_get_document_title', 'my_title');
function my_title() {
return 'Some title';
}
This is for the newer versions of WordPress. The old installations might be still using the legacy `wp_title()` function, which you already mentioned in your question. | stackexchange-wordpress | {

Remove "a href" from wp_list_comments()

'style' => 'ol',
'short_ping' => true,

?>
</ol>
I need to remove "a href" part.I mean their should not be linked to the comment author website.
I check `wp_list_comments()` from codex, but I could not find how to remove `<a href` part. | Deep down the function uses `get_comment_author_link()` to output the author name. That function is filterable. Inside the function it checks if the author has a URL and wraps the name in a link to it if it exists. We can use the `get_comment_author_link` filter to just output the name, and ignore the URL. This is pretty simple, since the callback for this filter gets the author name as one of its arguments, so we just need to pass it through untouched:
function wpse_284352_author_link( $author_link, $author ) {
return $author;
}
add_filter( 'get_comment_author_link', 'wpse_284352_author_link', 10, 2 );
**EDIT:** It's actually even simpler, the URL has its own filter, which means that can be filtered with one of WordPress' built in functions in one line:

What are the downsides of using bootstrap in plugin development?

* version conflicts;
* styling conflicts;
* script conflicts.
To minimize possibility of conflict and breakage you would need to consider following extra steps:
1. Importing _just_ the necessary Bootstrap styles into your stylesheet and making them specific to _only_ markup related to your plugin.
2. Only load JS scripts from Bootstrap that you need and putting them in `noConflict` mode, which will keep them out of global namespace and remap them so that only your plugin will make use of that specific instance. | stackexchange-wordpress | {

Why does my WordPress show a 404 message for 403 forbidden directories?

Unfamiliar HTML Properties in Avada and Divi Themes
I have looked at the DOM code for two WordPress themes that have tag properties that follow a pattern I have never seen before. These themes fit into the category of "framework themes", but I have not seen this use of properties in themes that stick closer to the WordPress codex. Here is an example: data-margin-right="0px" data-margin-left="0px" data-margin-top="31px" data-margin-bottom="31px"
When I do a Google search, it just picks up information about the default CSS rules: margin-left, margin-top, etc. I did figure out that CSS rules will override them, like it does other properties, within the normal specificity of CSS specifiers.
What is the story on these, ie. history, usage, constraints, etc? Should we look for this type of properties to show up in themes that more closely follow the WordPress codex. I have heard that WordPress is scheduled for a big technology change. | These are called data attributes, which are custom attributes in the format of `data-*` used to attach more info to the html elements.
This link here gives good examples on how to use them: <
Example:
<div id='el' data-my-attr='attr_value'></div>
**JavaScript** :
Most of the time, these info are used by JavaScript to fetch data and process them accordingly.
document.getElementById('el').dataset.myAttr; //Notice the property name uses CamelCase to replace the '-'s.
//Or using either of jQuery methods:
$('#el').data('myAttr');
$('#el').attr('data-my-attr);
**CSS** :
/* Use as selector */
div[data-my-attr='attr_value']{
/* styles */
}
And apparently you can also fetch its values using attr():
#el::before{
content: attr('data-my-attr');
}
So I guess one use for this is generating dynamic html and then set the CSS properties using the attr() in the CSS styles. | stackexchange-wordpress | {

Let Contributors Review only (Not Publish) Others Posts

Any ideas? Thanks in advance! | When something is available for other people to read, it is usually called "published". This all thing sounds like an overly complex way to have posts which can be read by anyone (since the contributor user is basically public info) with a comment section.
I suggest you give some more thought about why do you want feedback to be private (nothing is perfect, and no matter how much feedback you get there there will always be more), but in case you truly think this is the way to go, than just publish the post as private and let people that are interested in reviewing it create a new user in a subscriber role, and leave their feedback as comments.
